Step 1

Line an 8- or 9-inch square baking dish with parchment paper or aluminum foil, leaving some overhang for easy removal. Set aside.

Step 2

Add the white chocolate chips, sweetened condensed milk, butter, and salt to a large saucepan and place over medium heat. Stir continuously until the white chocolate chips are fully melted and the mixture is smooth.

Step 3

Remove from the heat and stir in the chopped Oreos until well combined.

Step 4

Scoop the mixture into the prepared baking dish and spread it around into one even layer. Top with additional chopped Oreos, if desired.

Step 5

Refrigerate for at least 3 hours or until fully chilled and the fudge is firm. Remove from the pan using the overhang from the parchment paper or foil, slice the fudge into pieces, and enjoy.
